Embodiment Construction

[0036] The manufacturing method of the radiator plate involved in the present invention.

[0037] The first implementation mode:

[0038] The manufacturing method of the radiator plate involved in the present invention can be realized by the following steps in sequence:

[0039] 1. Draw the electronic version of the light-drawing file. Convert the design file of the printed board into the corresponding light-drawing file of the heat sink in DXF format, and compile the program files required for the numerical control steps based on the file.

[0040] Described program file mainly comprises the file of drilling program, milling profile program, wire-cutting 3B instruction program; Drilling program file is the numerical control program when being compiled into drilling according to the hole position coordinate in the light drawing file; Milling profile program file is It is compiled according to the external dimensions and position coordinates in the light-drawing file; the wire...

Abstract

The invention provides a method for producing heat dissipation plates, which mainly comprises the following steps: 1) drawing an electronic Gerber file, and programming according to the Gerber file; 2) making a film according to the drawn Gerber file; 3) inputting the program made in step 1) into a machining centre device and a wire cutting machine, and carrying out digital control drilling and shape milling on the heat dissipation plate to be processed, then carrying out wire cut rectangular window machining; wherein in the process of digital control drilling, positioning holes and wire-feeding technology holes for positioning in the process of wire-cutting are produced; 4) carrying out countersunk treatment and plate erasing treatment on the heat dissipation plate subjected to digital control processing; and 5) carrying out surface treatment on the heat dissipation plate subjected to plate erasing treatment. The method provided by the invention is easy to realize, solves the problem of deformation occurred in the process of mechanical milling, and can be realized aiming at the plates with different design difficulties.

Description

technical field [0001] The invention relates to a manufacturing method of a heat dissipation plate. Background technique [0002] At present, the processing method of heat sink abroad is mainly the chemical milling method of aluminum alloy. The main reason is that under certain conditions, the aluminum alloy will be uniformly corroded by using an alkaline solution, and the appropriate protective material will be used for local protection, so that the non-protected parts will be uniformly corroded and the metal will be thinned to achieve the effect of mechanical milling. Primarily suitable for heat sinks where mechanical milling is not economical or possible. When chemical milling is used, the heat sink is milled in a free state, without deformation caused by external stress, and chemical milling can be performed on any part that can be contacted by the solution. [0003] Method flow: heat sink cleaning → coating of protective glue → vulcanization → engraving → chemical mil...
